Event detection unit

An event detection unit for detecting an explosive event, the event detection unit comprising:

• a plurality of different types of sensors, each sensor for measuring characteristics of an explosive event represented as a measurement;
• an event notification component;
• and
• a computing system with a processor for executing instructions stored in a non-transitory computer-readable storage medium, wherein the instructions when executed by the processor control the computing system to:
• for each sensor, receive a measurement for that sensor and generate a non-event probability and an event probability based on that measurement that indicates a likelihood that an explosive event has not occurred or has occurred, wherein the non-event probability for a sensor is based on a non-event probability distribution indicating probability of no explosive event given a measurement for that sensor and the event probability for a sensor is based on an event probability distribution indicating probability of an explosive event given a measurement for that sensor;
• determine whether an explosive event has occurred based on the non-event probabilities and event probabilities;
• and
• when an explosive event has been determined to occur, direct the event notification component to output a notification that an explosive event has occurred.
